Psychology- Gruen effect

In shopping mall design, the Gruen transfer / effect is the moment when consumers enter a shopping mall or store and, surrounded by an intentionally confusing layout, lose track of their original intentions, making them more susceptible to making impulse buys. So be careful while shopping in a mall and keep track of your shopping list.

The Gruen transfer is a psychological phenomenon in which an idealised hyper-reality is realized by deliberate reconstruction, providing a sense of safety and calm through exceptional familiarity.
